New to tri-valley – how is the life for kids?

Hello, I am a mom with 2 kids moving from Greater Boston. I would like to know the life of kids in California (espl. tri-valley) – with so many Indian families and kids and great weather, do kids get a chance to play outside everyday – Can I see communities where kids are outside playing? I really miss that here in my community here. I am wondering how is life for the  kids there? Are they constantly in shuttle between classes – How do the after school program look like – it is mostly enrichment and less play? If someone  can give me a perspective it will be greatly appreciated.
Thanks.
